User-centric connections to a location comprising digital collaboration tools

ABSTRACT

A method, device and system for providing user-centric connections to a location comprising digital collaboration tools, as well as software for carrying out the method. The method comprising a network device having a beacon system for proximity detection and a BYOD (Bring Your Own Device). A confirmed BYOD proximity can be used to initiate the setup of a data channel between the network device and the BYOD, and further join the BYOD to a UC (Unified Communications systems and tools) session.

Methods, devices and a system are described for user-centric connections to a location comprising digital collaboration tools as well as software for carrying out the method.

BACKGROUND

Communication within an enterprise environment (e.g. at companies, education sites, hospitals, entertainment locations, etc.) has changed and is moving away from location-specific behavior where a dedicated local device with a specific phone or video calling number was present. Wireless connections enable an employee to have access to the digital infrastructure almost anywhere within or in proximity of the enterprise building. However, while this technology can offer freedom, many solutions results in a complex user workflow when a user wants to connect to the resources at the present location. In many cases it is required of the user to book a meeting beforehand or to use a meeting room control panel in order to get access to the room resources, or to call a specific meeting room number to get connected.

SUMMARY OF THE INVENTION

The present invention can allow any enterprise room (for meetings, trainings, stage presentations, etc.) to become user centric with preferably very limited action from the user. Communication can be centralized e.g. within standardized Unified Communications (UC) system or tools environments, and using meeting rooms then becomes a different experience. Embodiments of the present invention can provide standardized and unified workflows to a collaboration environment. Hence embodiments of the present invention may overcome at least one of the above mentioned deficiencies,

For example, a user can walk into a room, be connected and start a UC meeting right from their laptop. Also the users can augment their capabilities with that of the meeting room (e.g. resources such as a room display, camera, microphones, etc.). Thus a user may use the room display to share locally, and use video and/or audio equipment to enhance communication quality in the meeting. By using embodiments of the present invention, sharing can be implemented both remotely and locally. The experience can be compared to what a user may have at his/her desk, so using room resources may not require any additional training or hurdles. Ultimately the user and his/her guests can enter a UC session in any room without having to follow or change pre-bookings, pre-configurations or other predetermined constraints.

Thus when a BYOD (Bring Your Own Device) is brought within a beacon system range the detected proximity can trigger an automatic set-up of configuring the room resource to become an extended resource to the user/BYOD or the UC session.

Consequently, the connection to the room resources may also be automatically terminated when there is no more BYOD within the proximity range of the local network device (while the ongoing UC session does not need to be terminated). Hence, the user/BYOD could enter another meeting room and connect ad-hoc to a network device and corresponding room resources of that room. There is no need to pre-allocate rooms or resources or consult a calendar tool to collect information on participants, but the connection authorization is based on that at least one of the BYOD's participating in a UC session, is located within the proximity range of a network device (beacon system).

Devices participating in a meeting can comprise BYODs located in the related meeting room, room resources in the meeting room and remote BYODs connecting via a UC (Unified Communications system or tools) session. There may also be BYODs inside the meeting room that are not connected to the UC session. Embodiments of the present invention allow to synchronize the connectivity status of the UC session between the UC session, a BYOD app and a network device app such that an action executed within the BYOD app can be subsequently executed within the BYOD UC session. For example, a BYOD operator can request a sharing action by performing an action with the BYOD app (e.g. pushing an icon), the BYOD app can then automatically communicate this request to the UC client and trigger the launch of the sharing action within the UC session.

It is an objective of the present invention to provide a room for meetings, trainings, stage presentations, etc. and a method of operating the room so that collaboration becomes more user centric with preferably very limited action from the user.

This has the advantage of changing the way meeting rooms and meetings are perceived by the users. The collaboration becomes more efficient because the time consuming procedures to join an electronic meeting are reduced.

In one embodiment of the present invention there can be provided a method for joining a network device UC client to a UC session connected to at least one BYOD UC client, the network device and the BYOD each can comprise a beacon transmitter configured to periodically or continuously transmit a beacon signal, or a beacon receiver configured to receive the beacon signal within its range, so that they can exchange the beacon signal, the beacon signal having a range, the network device can comprise an ID, a network device application (app) and a UC client, and the BYOD can comprise a BYOD app and a UC client, the method can comprise the steps of bringing the BYOD and the network device within the beacon signal range so that the BYOD and the network device can exchange a beacon signal comprising the network device ID, and generate and register an authentication-ID key, the exchanged beacon signal can trigger the BYOD app and the network device app to configure a data channel between them, the configured data channel can trigger the BYOD app to check if the BYOD UC client is connected to a UC session, if so, the BYOD app can send an invitation comprising the authentication-ID key to the network device app instructing the UC client to connect to the UC session, the network device app can check if at least one BYOD app that has a configured data channel to the network device app is also in the UC session, if so, the network device app can accept the invitation and instruct the network device UC client to connect to the UC session.

This has the advantage that a BYOD can be joined to a UC session without first starting the UC session or starting a login procedure (possibly on an additional device) but the UC session information transfer is enabled in the connection procedure itself.

Additionally, the method can comprise a second BYOD, the network device and the second BYOD each can comprise a beacon transmitter configured to periodically or continuously transmit a beacon signal, or a beacon receiver configured to receive the beacon signal within its range, so that they can exchange the beacon signal, the beacon signal having a range, the second BYOD can comprise a second BYOD app and a second UC client,

This has the advantage that a second BYOD user entering a meeting room can automatically be joined by merely walking into the meeting room. The UD session moderator does not need to invite the second person or BYOD.

Additionally, the network device and the BYOD can comprise a second beacon system having a range for proximity detection and comprising a beacon transmitter configured to periodically or continuously transmit a second beacon signal, the method can comprise bringing the network device and the BYOD within the range for proximity detection, the second beacon system can exchange a second beacon signal, which can trigger the transmitter of the first beacon system to periodically or continuously send out a first beacon signal during a limited amount of time or until a data channel has been configured between the network device and the BYOD.

This provides the possibility to not continuously transmit the warble (the first beacon signal).

Additionally, the method can comprise a step of registering a data channel between the BYOD and the network device which can be preceeded by the BYOD confirming to connect with the network device.

This makes sure the BYOD connects to the correct network device.

Additionally, the BYOD can comprise an BYOD identity, and the method can comprise a step of registering a data channel, the method can comprise the BYOD app requesting authentication with the network device app for the BYOD identity.

Additionally, the method can comprise step of registering a data channel, the method can comprise the network device computer program product generating and registering an authentication code with the BYOD identity.

Additionally or alternatively, the network device can be connected to a room resource having input and output signals, and the method can comprise the step of the network device app controlling the input and output signals of the room resource.

Additionally or alternatively, the BYOD app can adopt a BYOD app state and the BYOD UC client can adopt a BYOD UC client state, the method can comprise the step of the BYOD app bringing the BYOD UC client state equal to the BYOD app state.

This has the advantage that the BYOD operator may share content via a UC session or via local sharing but the same outcome will be obtained, e.g. that the content is shown on a room display.

Additionally, there can be a third BYOD present, having a BYOD app and no BYOD UC client, the method can comprise when the network device is connected to a UC session, the third BYOD app can share content to the network device app, the network device app can share the content to the network device UC client which then can share the content in the UC session.

This enables a BYOD having no UC client to still participate in the UC call if the BYOD is located within a meeting room that has a network device connected to the UC session. The content can be shared in the UC session and the UC session can be shared via the room display.

In another embodiment of the present invention there is provided a system for joining a network device UC client to a UC session connected to at least one BYOD UC client, the network device and the BYOD each can comprise a beacon transmitter configured to periodically or continuously transmit a beacon signal, or a beacon receiver configured to receive the beacon signal within its range, so that they can exchange the beacon signal, the beacon signal having a range, the network device can comprise an ID, a network device app and a UC client, and the BYOD comprises a BYOD app and a UC client, if the BYOD and the network device are positioned within the beacon signal range, there can be an exchange of a beacon signal between the network device and the BYOD, wherein the beacon signal can comprise a network device ID and a corresponding authentication-ID for authorizing the BYOD UC client to connect to the UC session.

The system enables a procedure where a BYOD can be joined to a UC session without first starting the UC session or starting a login procedure (perhaps on an additional device) but the UC session information transfer is enabled in the connection procedure itself.

DEFINITIONS

A “BYOD” (Bring Your Own Device) can be computational processing devices comprising laptops, mobile phones, smartphones, tablets, palm pads and the like. In the present context it may also include a stationary computer. The computational processing device has means for providing content that can be outputted on an internal or external display device.

In accordance with the present invention the term “network device” relates to a network enabled digital processing device such as a Personal Computer (PC) or a work station having some form of display of information such as a display screen or one or more of a projector or other visible, audio or tactile displaying device. A network device has a processing engine, i.e. digital processor such as an FPGA or a microprocessor, having e.g. a Central Processing Unit (CPU) and/or a Graphical Processing Unit (GPU) and memory as well as interfaces such as a serial port or a network interface. A network device in operation is connected to a network, can access this network and use the facilities of the network as well as having local capabilities, applications, functions etc. For example, a network device in a meeting room can control access and manipulation of resourses connected to it. Example of such resources can be displays, loudspeakers, microphones, furniture, lighting, temperature, etc. The network can be a shared resource network such as a Local Area network (LAN), Wide Area Network (WAN), Metropolitan Area Network (MAN), or a data network such as the Internet or can include combinations of these.

A network device as used with respect to the present invention generally does not relate to hardware that only mediates data in a computer network such as gateways, routers, bridges, switches, hubs, repeaters, multilayer switches, protocol converters, bridge routers, pure proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, modems, ISDN terminal adapters, line drivers, pure wireless access points, networking cables and other related hardware.

A network device can make use of a Network Access Device (or NAD) being an electronic circuit that automatically connects the network device to a network such as a preferred network. A NAD is any device that, when connected to, provides access to a larger communication network of some sort.

“Unified Communications system or tools” or UC refers to audio or audio visual communications such as provided by “Skype™” or “Skype™ for business”. Such software can take over audio and/or visual data provided from a host processing device. Unified communication tool can be described as a collection of tools to do VOIP, (web) conferencing, shared whiteboarding, message exchange (e.g. chat), file transfer, or presence. Unified Communications system or tools can make use of a protocol- or standard defined or specific communication session or interaction, such as Voice-Over-Internet-Protocol (“VoIP), text or instant messaging (e.g., AIM, Blauk, eBuddy, Gadu-Gadu, IBM Lotus Sametime, ICQ, iMessage, IMVU, Lync, MXit, Paltalk, Skype, Tencent QQ, Windows Live Messenger™ or MSN Messenger™, Wireclub, Xfire, and Yahoo! Messenger™ email, Twitter (e.g., tweeting), Digital Service Protocol (DSP), and the like. Unified Communications system or tools can make use of video conferencing cloud service including a video conferencing node to allow one or more users located at the first video conferencing endpoint to communicate with one or more users located at the second video conferencing endpoint in a video conference.

UC can be implemented as central computer program products on one or more remote servers connected with local computational devices. Local computational devices can comprise a local computer program product (a so-called client) that can access a central UC. Thus, a “UC session” can run on the remote server and be accessed by one or more local “UC clients” which can hereby exchange content. In the present context the term “UC” also comprises variants such as e.g. “Unified Communications & Collaboration (UC&C), Unified Communidations as a Service (UCaaS), Video conferencing solutions or similar solutions that allow audio and video communication both locally and remote.

A “beacon system” can comprise a beacon transmitter and a beacon receiver configured to send and receive a beacon signal. A beacon transmitter or transceiver is a device designed to attract attention to itself and/or its capabilities by means of sending wireless signals that can be read and parsed by any suitable transceiver or receiver within range or distance. Beacons can be low power transmitters that and unlike full communication with a base unit or station, do not need to carry traffic data. For example, pilot signals can operate as beacons, such pilots only transmitting in the pilot channel of a wireless telecommunication system. A beacon can transmit and receive signalling information including access requests and grants. Some beacons can also transmit and receive traffic data. For example a video stream captured by a camera associated with a network device can be sent to a mobile device over the beacon channel, or by other means such as over a network via the at least one server. Hence, if the beacon is reserved for signalling only this transfer of traffic, i.e. video stream) would not go via the beacon but via another wireless channel.

In any of the embodiments of the present invention it is specifically disclosed by this paragraph that a beacon can be a means for short distance communication, for example Bluetooth, Bluetooth Low energy, Near Field Communication, Zigbee, Li-fi.

A simple means for short distance communication related to proximity detection can be implemented with a loudspeaker (beacon transmitter) and a microphone (beacon receiver). The exchanged audio signal can be referred to as a “warble”.

The proximity- or beacon range of a beacon system can be expressed in a distance and such range may additionally be limited e.g. by the walls of a room.

A software application or “app” can be a computer program product which is configured to handle exchange of data between devices in a digital or computerized system.

An app can be located on a remote application server and accessed via local clients. Apps can execute dedicated tasks on computerized devices.

A BYOD app, a network device app or a UC client can adopt a “state” related to e.g. connection- or sharing status. For example a BYOD app state or just BYOD state can be “not connected” to a network device, or it can be “connected” and “sharing UC content”, etc. The present invention allows to synchronize the connectivity and sharing status between a device app and a UC client on either type of device. For example, if content is shared from a BYOD app, the app automatically triggers the BYOD UC client to share the same content in a UC session. Since a room display can be participant in the UC session (via the network device UC client) and share its content to all participants in the UC session, both those participants within the meeting room and remotely located participants can receive the shared content.

A “media data stream” comprises visual and/or audible content, for example images, recorded videos, real-life camera streams, documents, etc., that can be inspected on any display device in a collaboration platform. Additionally or alternatively, a data stream may contain audio data or meta data such as keyboard and mouse events.

A “room” is a space inside a structure or building, e.g. usually, a room is separated from both other rooms and the outside by walls and a ceiling. Each room usually has a specified purpose, in the present case a meeting room or conference room, defined by its use and the equipment therein to achieve this purpose. A room can have a 15 dB attenuation of wireless signals passing through the walls of the room.

DETAILED DESCRIPTION

In the present context, a user is an operator or person using a BYOD. For convenience, the following text may use a “room display” as example of a room resource, but the present invention is not limited hereto but can comprise any resource that can be controlled by a network device such as e.g. loudspeakers, videocameras, microphones, lighting, thermostats, projector devices, electronic white boards, room furniture, etc.

FIG. 1 shows an embodiment of the present invention comprising a confined space or room 10. Inside the room 10 there is a BYOD 11 and a network device 15 which can control a room display 14. The network device 15 can be connected to the room display 14 via channel 20, which may be wireless or cabled. The BYOD 11 can comprise a beacon receiver 12 which can receive a beacon signal 17. Further the BYOD 11 can comprise a UC client 13 which can be connected to an active UC session on a UC server 21. The UC server 21 can be located elsewhere on a off-premise server (often “in the cloud”).

The network device 15 can comprise a UC client 24 that can connect to a UC session at the UC server 21. The network device 15 can further comprise a beacon transmitter 16 which can transmit the beacon signal 17. The beacon transmitter 16 and beacon receiver 12 can be referred to as a beacon system 22 having a proximity range.

The proximity range may be the largest value of the distance 23 that the transmitter and receiver can be separated and still exchange a signal. The largest value of the distance 23 may also be limited by the walls of a room. This can occur when the walls and ceiling of a room provide an attenuation of wireless signals such that the signal outside a room does not have sufficient energy for communications to be sustained. If a multiple of BYOD's are participating in the UC session (the BYOD's may be located within the room 14 or connecting remotely) it may be desirable to share the content of the UC session to the room display 14.

It may also be desirable to share the content of the room display 14 to all participating BYOD's. For example, if one participant is sharing to the room display 14 without using the UC session, it's advantageous if the all BYOD's can also receive that content. This may be implemented by making the network device 15, which the room display 14 is controlled by, participant of the UC session, so that content can be shared from the room display 14 to all participants, independent of the channel used to provide the content to the room display 14.

The present invention comprises a software application or “app” in the form of a network device app 18 and a BYOD app 19. The apps 18 and 19 can be configured to monitor and perform actions related to the exchange of data between the BYOD and the network device. The apps 18 and 19 can be configured so that certain data transfers can trigger the apps to perform an action. In this way the BYOD can receive necessary data for e.g. establishing a connection to a resource device, with limited need of input from the BYOD operator. The present invention can provide a user-centric approach where the environment can react to the presence of a BYOD and be configured to adapt hereto.

FIG. 2 shows a flow chart of an embodiment of the present invention describing the event of how to automatically join a network device (and hereby a room resource) to a UC session.

In step 40 the BYOD 11 is brought into the meeting room 10. The beacon transmitter 16 can periodically or continuously send out a signal, for example a signal that cannot be perceived by human beings such as an ultrasound signal, e.g. a warble, a UV or infrared signal such as a diverse UV or infrared signal or an optical light signal which is modulated at such a high frequency that the human eye cannot detect it. The signal is broadcast within a room awaiting that a suitable receiver enters within the proximity or beacon range.

In step 41 the beacon system 22 detects that BYOD 11 and the network device 15 are located within the proximity or beacon range of the beacon system 22. The proximity detection (e.g. comprising that a beacon signal has been received by the beacon receiver) can trigger the BYOD app 19 to connect with the network device app 18. This step may be preceeded by the BYOD app 19 receiving a confirmation to connect from the BYOD 11, e.g. the user of the BYOD 11 may be requested to confirm that he/she wants to connect to the network device 15. The event of connecting the BYOD app 19 with the network device app 18, can trigger the BYOD app 19 to check if there's an active UC session connected to the BYOD UC client 13 (step 43). If an active UC session is confirmed, the BYOD app 19 can send an invitation to the network device UC client 24 to join the UC session (step 44). In step 45, the network device app 18 can check for each BYOD connected to it if at least one of the connected BYOD also have a UC client connected to the UC session. (If a UC session has no BYOD's in a room, there is no use connecting the room display or other room resource to the UC session.) If this is confirmed, the network device app 18 accepts the invitation to join the UC session (step 46). With the procedure described in FIG. 2, the room display 14 can be made available as participant so that any content displayed on it can be shared to all participants in the UC session. This is independent of how the content was provided to the room display 14.

It would be possible to have a local BYOD, which is not connected to the UC session, in the meeting room of a network device. The network device (and related room resources) could be connected to a UC session via a remote BYOD which is in the UC session. The local BYOD could connect locally to the room display (and other room resources) and hereby participate in the UC session without having a UC client.

FIG. 3 shows an embodiment of the present invention comprising rooms 60 and 80 within the same premise and a remote room 90. All devices in FIG. 3 can transmit or receive a beacon signal and comprise a beacon transmitter or receiver respectively (c.f. FIG. 1), however the latter have been left out for clarity. The room 60 comprises a network device 61 which can transmit a beacon signal 62, and a network device app 63 and a UC client 64. The BYOD 65 can receive the beacon signal 62, and comprises a BYOD app 66. The BYODs 67, 70 can receive the beacon signal 62 and comprises a BYOD app 68, 71 and a UC client 69, 72, respectively. Room 80 comprises a network device 81, which can transmit a beacon signal 82, a network device app 83 and a UC client 84. The BYOD 85 can receive the beacon signal 82, and comprises a BYOD app 86 and aUC client 87. The remote room 90 comprises a BYOD 91 which in turn comprises aUC client 92. All device apps 63, 66, 68, 71, 83 and 86 communicates with one or more servers hosting the application cloud 100 via a signaling channel 101, which can comprise a LAN, Wireless or any similar network. Each UC client can connect to a UC session (not shown) on the UC server, and communicates with a UC server 111 via a UC channel 110, which can comprise LAN, Wireless or any similar network. Content, such as media data streams, can be shared among the BYODs via a data stream channel 120 which can comprise LAN, Wireless or any similar network.

FIG. 4 shows a flow chart of an exemplary embodiment of the present invention comprising the different actions carried out by a BYOD operator 150, the BYOD 11 (from FIG. 1), the network device 15 (from FIG. 1) and a UC server 21 during a connection scenario. For this case there is not yet any other BYOD connected to the network device 15. While the flow chart in FIG. 2 gives an overview, the present flow chart emphasizes the interaction between the different devices.

The BYOD 11 and the network device 15 each comprises a beacon system 22 and an app 19 and 18 respectively. The operator 150 and the BYOD 11 enters the room or location where the network device 15 is located, and turns on the BYOD 11. The beacon systems sends out periodically or continuously a beacon signal, for example a signal that cannot be perceived by human beings such as an ultrasound signal, e.g. a warble, a UV or infrared signal such as a diverse UV or infrared signal or an optical light signal which is modulated at such a high frequency that the human eye cannot detect it. In the present scenario, the beacon system can comprise a loudspeaker on the network device 15 for periodically sending out a sound signal such as an ultrasound signal e.g. a warble 162 which can be detected by the BYOD 11 via its app in step 163.

Alternatively there can be a second beacon system for proximity detection present which can detect that BYOD devices are located within its beacon range and trigger the network device to send out a warble with connection details (using the first beacon system). The warble could then be transmitted e.g. during a limited amount of time, or until all BYODs within the range of the proximity beacon system have connected to the network device. This solution provides the possibility to not continuously transmit the warble.

The BYOD 11 displays an invitation to the operator 150 to confirm that the BYOD 11 should be connected to the network device 15. The operator 150 confirms the BYOD 11 should be connected (step 165). The BYOD app connects to the network device 15 (step 166), the network device 15 confirms the connection (step 167). The user interface communicates the confirmed connection (step 267). The operator 150 clicks on a UC call (or session) invitation displayed on the BYOD 11, and the UC client requests the UC server 21 to start a UC session (step 169), and the UC server 21 confirms the UC client of the BYOD 11 is connected to the UC session (step 170). The app of the BYOD 11 detects the active UC session (step 171), and this triggers the app of the BYOD 11 to invite the network device UC client to the connect to the UC session (step 172). The UC client of the network device 15 request to the UC server 21 to connect to the UC session (step 173), and the UC server 21 confirms the request (step 174) and the the network device 15 connects to the UC session (step 175).

Once (the UC client of) the network device 15 is connected to the UC session, further BYODs can connect directly to the network device 15 via their UC clients.

FIG. 6 shows flow charts 200 and 205 of embodiments of the present invention where the UC client of a BYOD is initially connected to a UC session and the BYOD is connected to a network device and where the BYOD disconnects from the UC session or disconnects from the network device.

The flow chart 200 illustrates a scenario when one BYOD leaves the beacon range so that the connection to the network device is broken, or closes the connection to the UC session (step 201), but there is still another BYOD within the beacon range connected to the network device. The UC client stops accessing the UC session (step 202). The stopped call is detected by the BYOD app (203) and the BYOD app disconnects the BYOD from the network device (204).

The flow chart 205 illustrates a scenario when the last BYOD within the beacon range moves out of the beacon range. The BYOD app detects that the BYOD is no longer within the range (step 207). The BYOD app disconnects the BYOD from the network device (step 208) and the network device UC client disconnects from the UC session (step 209).

FIGS. 7 to 9 show state diagrams of embodiments of the present invention. In each state diagram, the black dot is the start point and each arrow is an event. A rectangular block represents the state of the device after an event; several events can lead to the same state. A diamond symbol represents a point of choice where several events can be possible, often depending on the environmental conditions.

In the text describing FIGS. 7 to 9, the simplified expression “join a UC session” will be used for a BYOD or a network device. This can comprise (as described in FIG. 4 and related text):

-   -   the BYOD and the network device connect to each other, if they         are not already connected, and/or     -   the BYOD UC client and/or the network device clients are         activated and access a UC session (running on a UC server).

A BYOD or a network device can “leave a UC session” by no longer accessing the UC session.

Further, the “beacon range” is the range of the beacon system, described in FIG. 1 and related text. “Local content” is shared by means other than via the UC session. “UC content” is shared within the UC session.

The state diagram 300 in FIG. 7 shows possible states for a network device. At starting point 301 the network device app is started or activated 301 and goes to “ready” 302. In event 303, a BYOD can “join a UC session” when it is located within the “beacon range” of the beacon system. Alternatively, the BYOD has already joined a UC session and then enters the “beacon range” of the beacon system. Event 303 ends with a point of choice 304, comprising the possibility of the BYOD to not share content 305 or to share content 306. Both 305 and 306 leads to state 307 where the network device is connected to a UC session. State 307 comprises the sub-states of UC content “not shared” 308 or “shared” 309. Additionally or alternatively, the BYOD can share “local content” 310 to the network device. Within state 307 there can be a change between sub-states 308 to 310, for example via 311 where the BYOD stops sharing local content or UC content, or via 312 where the BYOD shares UC content via the UC session, or via 313 where the BYOD shares local content. From state 307, the BYOD can leave the beacon range or “leave the UC session” 314 to end up in a point of choice 315. If there is still a BYOD located within the meeting room 316, the network device will remain in the UC session and state 307. If there is no more BYOD located within the meeting room 317, the network device UC client disconnects from the UC session and returns to “ready” 302. If a BYOD is located within the meeting room and connected with the network device, which is in state “ready” 302, the BYOD can share local content 318 to the network device, which adopts the state “content shared locally” 319. If a connected BYOD stops sharing locally, or leaves the beacon range 320, the network device returns to “ready” 302. Of a connected BYOD starts a call when located within the beacon range, or brings a call into the beacon range 321, the network device goes to the point of choice 304, described above.

The state diagram 340 in FIG. 8 shows possible states for a BYOD. At starting point 341 the BYOD is located outside a beacon range related to a network device. The BYOD app is started 342 and the BYOD adopts the state “not in meeting room” 343. The BYOD can now be connected to the network device manually 344 and arriving at a point of choice 345. Alternatively, the BYOD can enter within the beacon range 346 and adopt a “detected” state 347. The BYOD can now be offered to connect to the network device and adopt sub-state “connection offered” 348. The BYOD may ignore the offer and adopt sub-state “ignore” 349, or the BYOD can accept the connection 350 and arrive at the point of choice 345. From the state “ignore” 349 it is also possible for the BYOD to request a connection 351 in order to arrive at the point of choice 345. The BYOD can leave 352 the detected state 347 and arrive at the state “not in meeting room” 343. The point of choice 345 may comprise “no ongoing UC session” 353 whereby the BYOD will adopt the state of “connected” 354 and its substitute “not sharing” 355. Alternatively, there can already be an ongoing call that the BYOD joins 356 whereby the BYOD adopts the connected state 354 and its sub-state “shared UC session” 357. From the “not sharing” 355, the BYOD can share locally 358 and adopt “sharing locally” 359 and again stop sharing 360 and return to “not sharing” 355. Alternatively, the BYOD can adopt the state of “shared UC session” 357 by starting from “sharing locally” 359 and start or join a UC session 361, whereby the UC sharing can be given priority over local sharing so that the local sharing is stopped. Alternatively, starting from the BYOD “sharing locally” 359, the network device can stop the local sharing from the BYOD and join a UC session 362 so that the content from the BYOD can now be shared via the UC session. Further, from the “not sharing” 355, the BYOD can start a UC session or join an ongoing UC call (or session) and adopt “shared UC session” 357. Alternatively, the netowrk device can join an ongoing UC session 364 and adopt “shared UC session” 357. From the “shared UC session” 357, the BYOD can leave the UC session 365 and return to “ignore” 349. From any of the “connected” 354 states, the the BYOD can disconnect 366 from the network device and return to “ignore” 349 or the BYOD can be brought out of the beacon range 367 and return to the state “not in meeting room” 343.

The state diagram 380 in FIG. 9 shows possible states for a BYOD which does not have a UC client installed. At starting point 381 the BYOD is located outside a beacon range related to a network device. The BYOD app is started 382 and the BYOD goes to state “not in meeting room” 382. The BYOD can now be brought into the beacon range 383 and adopt the state “not sharing” 384. If the BYOD leaves the beacon range, it will return to “not in meeting room” 382. Alternatively, if the BYOD shares content locally 385 to the network device (which is not in a UC session) it can adopt the state “sharing locally” 386. The BYOD can now stop sharing 387 (and another BYOD can start sharing) so it returns to the “not sharing” 384. Alternatively, starting from “sharing locally” 386, the BYOD can be brought out of the beacon range 388 and return to “not in meeting room” 382.
